The Mountain Chorus Frog is found in and around the Appalachian Mountains in the eastern United States. The frog starts breeding when they wake up from their hibernation generally around late February and early March. The males call sounds like reeking sound. Females can lay 300 to 1500 eggs in a clutch. No parental care has been reported in the Mountain Chorus Frog. The eggs hatch in 7-10 days and the tadpoles undergo metamorphosis in a month or two. The Mountain Chorus Frog is a terrestrial species of tree frog. They spend most of their time on the ground.

least concern
Common Name: Pig Frog
Scientific Name: Lithobates grylio
Family: Ranidae – True Frog Family
Locations: United States – Alabama, Florida, Georgia, Louisiana, Mississippi, South Carolina, and Texas
Introduced Locations: Bahamas, China, and Puerto Rico.
Size: 6.5 inches (165 mm)

The Pig Frog is named after the male’s mating call that sounds like a pig grunt. Like most frogs in North America, the Pig Frog breeds from early spring to late summer. Generally, the frog breeds in permanent bodies of water such as ponds, lakes, and swamps but have been known to breed in ephemeral ponds, streams, and roadside ditches. Females can lay up to 15,000 eggs during a breeding season. The Pig Frog is mostly aquatic, only coming to the edge of bodies of water.

New Species

New Species and Genus from the Western Ghats of India

fig-3-2x.jpg

A new species of frog was discovered in the Western Ghats of India. The Western Ghats is an incredible place to go frogging. There are three known families of frogs that are only found there and hundreds of different species of frogs. Not only was this new species discovered, it has been put into a new genus by itself and its own new subfamily.

Researchers decided on the common name  of the new frog as the Starry Dwarf Frog (Astrobatrachus kurichiyana) after the light spots on their body that resemble stars. The genus name also reflects that stars,  astro meaning star in Greek and batrachus meaning frog. The species epithet, Kurichiyana, is the name of the local tribal community living near the frogs. The Starry Dwarf Frog is a member of the family Nyctibatrachidae, a fairly new family. The family is only found in India and Sri Lanka. The new subfamily is named Astrobatrachinae.

The conservation status of the frog is currently unknown. Not much really is known about the Starry Dwarf Frog. What is known is that it is mainly terrestrial and nocturnal.  They are a small species of frogs, only growing to an inch long.

Common Name: Marbled Balloon Frog
Scientific Name: Uperodon systoma
Family: Microhylidae
Locations: Bangladesh, India, Nepal, Pakistan, Sri Lanka
Size: 2.5 inches

The Marbled Balloon Frog spends most of its life underground, only coming to the surface during the summer monsoons from May to July. They have powerful hind legs, that help them burrow deep in the ground. One frog had been found over 3 feet deep. The frog lacks any teeth, due to their diet of mainly termites and ants.

Cope’s Gray Tree Frog (Hyla chrysoscelis)

GrayTreeFrog
least concern
Common Name: Cope’s Gray Tree Frog
Scientific Name: Hyla chrysoscelis
Family: Hylidae
Locations: United States and Canada
US Locations: Alabama, Arkansas, Washington D.C., Delaware, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Mississippi, North Carolina, Nebraska, New Jersey, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia, Wisconsin, and West Virginia
Size: 2 inches

The Cope’s Gray Tree Frog is almost identical to the Eastern Gray Tree Frog (Hyla versicolor) besides their calls and chromosome count. The Cope’s Gray Tree Frog is diploid while the Eastern Gray Tree Frog is tetraploid.

The frog is named after Edward Drinker Cope, the man who first described the frog to western science. Edward Drinker Cope described a lot of different species, over a thousand living and dead species. While the frog is named the Gray Tree Frog, it can also be green in color.

Crawfish Frog (Lithobates areolatus)

nearthreatened
Common Name: Crawfish Frog
Scientific Name: Lithobates areolatus
Family: Ranidae – True Frogs
Locations: United States – Alabama, Arkansas, Iowa, Illinois, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Oklahoma, Tennessee, and Texas
Size: 4.4 inches (113 mm) long for females, 4.1 inches (105 mm) long for males

The Crawfish Frog is named after the fact that they live in the holes of crawfish. They use the holes for protection from predators. In the northern part of their range, they use them to get below the frost line to prevent them from freezing to death.

Breeding occurs from January to May following rain fall. In the northern parts of their range, they breed later from late February to May while frogs in the southern parts of their range breed from January to April. After the rains fall and temporary ponds of water are formed by the rain, the male Crawfish Frogs migrate to these ponds and start calling. Female frogs follow shortly after. Crawfish Frogs are explosive breeders with most of the mating happening right away at the start of the season.

One noticeable characteristic of the male Crawfish Frog is their lateral vocal sacs which is not often seen in frogs in the US.

There are two sub species of the Crawfish Frog, the Northern (Lithobates a. circulosa) and Southern (Lithobates a. areolata).

Lowland Burrowing Tree Frog (Smilisca fodiens)

least concern
Common Name: Lowland Burrowing Tree Frog, Northern Casquehead Frog,
Scientific Name: Smilisca fodiens
Family: Hylidae – Tree Frog family
Locations: Mexico and the United States
US Location: Arizona
Size: 2.5 inches

The Lowland Burrowing Tree Frog is not your typical tree frog, it doesn’t live in the trees, it lives in burrows. It lives in the desert so the they need to keep moist. The burrows they live in are very moist. If the moisture leaves during periods of drought, the Lowland Burrowing Tree Frog can create a cocoon out of their outer skin to help keep them moist. After the rains come and the frog doesn’t need the cocoon anymore, the frog will break out and then eat the cocoon.

Granular Poison Frog (Oophaga granulifera)

vulnerable
Common Name: Granular Poison Frog
Scientific Name: Oophaga granulifera
Family: Dendrobatidae – Poison Dart Frog family
Locations: Costa Rica and Panama
Size: .7 – .8 inches (18-22 mm)

The Granular Poison Frog is a diurnal (active during the day) species of frog. The males of the species are highly territorial in regards to their calling and breeding sites, even attacking other males. After breeding, the males will brood the eggs and keep them moist. After the eggs hatch, the females transport the tadpoles on their back to a water-filled plant. The females will lay unfertilized eggs for the tadpoles to feed on. The Granular Poison Frog is listed as Vulnerable by the IUCN due to habitat destruction and habitat fragmentation. Logging, agriculture, and expanding urbanization are causing this.

Common Name: Northern Red-legged Frog
Scientific Name: Rana aurora
Family: Ranidae
Locations: Canada and the United States
US Locations: Alaska, California, Oregon, and Washington
Size: 3.3 inches

The Northern Red-legged Frog is found along the western coast of North America. They breed from January to March depending on how far north they are located. Farther north they are, the later they breed. Egg masses from the frogs number between 300 and 5000 eggs. Eggs hatch in about a week into tadpoles. The tadpoles take 3 to 7 months to fully undergo metamorphosis. Some of the tadpoles take until the next spring to turn into frogs. Adult frogs can live up to 10 years.

Cuban Tree Frog (Osteopilus septentrionalis)

Common Name: Cuban Tree Frog
Scientific Name: Osteopilus septentrionalis
Family: Hylidae – Tree Frog Family
Locations: Bahamas, Cayman Islands, Cuba
Introduced Locations: Anguilla, Costa Rica, Guadeloupe, Puerto Rico, Turks and Caicos Islands, United States (Florida, Hawaii, Louisiana, Georgia, Alabama, Mississippi, and Texas), British Virgin Islands, and US Virgin Islands.
Size: 3 to 5.5 inches

The Cuban Tree Frog is a large tree frog native to the Caribbean but has been introduced to other areas of the world such as Florida. In Florida, the Cuban Tree Frog has become a problem. Their size allows them to eat other smaller frogs and other native animals.  They also can breed year round and it takes only a couple weeks for the tadpoles to reach frog stage. They also can produce skin secretions that can irritate humans.
